BSTFLEX adhesive backed lava shield made from crushed volcanic rock, it has heatshielding capabilities with a carbon-fiber look. This insulator helps to reflect and dissipate heat, making it perfect to be an airbox heatshield or heatshield barrier to protect the paint on your carbon-fiber/fiberglass hood. Due to the natural chemical and acid-resistant properties of basalt (a mineral from volcanic rock), BSTFLEX adhesive backed lava shield  is excellent to use in harsh environments.

BSTFLEX adhesive backed lava shield may be used on a firewall to shield radiant heat, and is also perfect to shield heat in transmission tunnels. Keep the look of carbon fiber but have the functionality of BSTFLEX adhesive backed lava shield heat barrier. It can be used with less than 1 inch of airspace, but 1/2 inch minimum is recommended. It is also better to use BSTFLEX adhesive backed lava shield on applications where there is little airflow, making it a superior insulator to aluminum and gold barrier fabrics in these conditions. BSTFLEX adhesive backed lava shield withstands 1,200 degrees F direct continuous temperatures and 2,000 degrees F intermittent.

Why don't you recommend using adhesive backed lava shield on rough, unfinished fiberglass or carbon?

A. Self adhesive backings cannot fill in the surface irregularities that occur on unfinished glass or carbon. For these applications, it is better to use a spray on adhesive

Can I cut the adhesive backed lava shield and "overlap it"?

A. Lava Shield cuts easily with a pair of scissors of a utility knife. We do not recommend trying to overlap the Lava Shield, because of it's coating. The coating may prevent the adhesive backed lava shield s adhesive to stick
